The human body is made with different kinds of immunity, which protects it from anything that could harm the body. During an allergic reaction, the immune system erroneously believes that what have entered the body are harmful, thus producing antibodies called IgE (immunoglobulin E) antibodies to protect itself from the harmful element. It then circulates through the blood forming IgE's, which are specific to something as light as food. After this food-specific IgE is formed, it attaches itself...

Polychlorinated biphenyls, PCBs, are organic, chlorinated chemicals that are synthetically produced from manufacturing companies. The high chemical properties and low reactivity of the compound allows the toxin to be useful in industrial applications such as coolant fluids and dielectrics. Although the toxin has been banned in the United States since 1976, its presence has been accumulated in the environment in areas such as air, water, sediments, and soils. PCBs are able to accumulate in...

Based on the change in electrochemical behavior of enzymatic activity, six kinds of acetylcholinesterase biosensor have been devised for investigation of electrodes sensitivity using different modified methods. Electrochemical impedance spectroscopy (EIS) and cyclic voltammograms (CV) were used to investigate the electrochemical response of the six different modified glassy carbon electrodes, respectively. The results shown that the gelatinous composite containing functional multiwall carbon...

Ubiquitination, one of the most important post-translational modifications of proteins, occurs when ubiquitin (a small 76 amino-acid protein) is attached to lysine on a target protein. It often commits the labeled protein to degradation and plays important roles in regulating many cellular processes implicated in a variety of diseases. Since ubiquitination is rapid and reversible, it is time-consuming and labor-intensive to identify ubiquitination sites using conventional experimental...

The standard rules of genetic read-out are very well known and written in every Molecular Biology textbook (Baranov et al, 2002b). Unconventional decoding, commonly referred to as recoding is utilized by many genes, a list of which can be found on the Recode database (Bekaert et al, 2010). Recoding refers to the dynamic shifts between open reading frames and redefinition of codon meaning at specific sites, programmed by signals in m RNA, which permits versatility of gene expression (Baranov et...

A biomarker is a biological marker. It is an indicator to reflect and identify normal or diseased state of the body (biological state), such as organ function, progressions of a disease, and effects of treatment. They are separated into three specific types of biomarkers: biomarkers of exposure, biomarkers of effect or biomarkers of susceptibility. There are several desired characteristics for a biomarker. Sample collection should be simple and reliable for diagnostics. Blood, urine or saliva...

Combustion is initiated by heating a plastic material to its decomposition point. The three critical sources required to sustain combustion process are ignition source, fuel and oxygen. The combustion cycle can be stopped by isolating any of the above mentioned sources. Numerous combustible decomposition products like hydrocarbons, hydrogen and carbon monoxide are formed. Flame retardance is chemical that added in product as to prevent or protect the product from being damaged by fire accident....

ABSTRACT Background and Objectives: There is a profound inclination among people toward consumption of herbs and herbal products. Some of these products are harmful while health promoting potentials of some others should be discovered. In the present study the antibacterial, antioxidant, acute and subchronic and cancer cell toxicity of methanolic and aqueous extracts of Rosa damascena Mill. were studied. Material and Methods: Antimicrobial activities were determined by agar disc diffusion...

The purpose of this essay is to explain the genetic disorder sickle cell anaemia in detail. This essay will introduce the genetic disorder and evaluates information to make a recommendation for Jonathon's situation. Red blood cells (RBCs) contain an iron-rich protein called "Haemoglobin". Sickle cell anaemia is a blood syndrome that affects haemoglobin in the RBCs. It is needed to bring oxygen from the lungs to the body (Emel, 2010). Normal red blood cells have haemoglobin A....

Action potential in the heart involves different conductions of ionic currents, which plays an important role the heart's conductance pathway, contraction and relaxation of the ventricles, and also in determining the duration. In this dissertation, I will be mentioning about the different ionic currents and voltage-gated channels which are involved in the heart's action potential. Further research studies were done to expand the details on the roles of the specific ionic currents /...
